In-Field Absolute Calibration of Ground and Airborne VIS-NIR-SWIR Hyperspectral Point Spectrometers
Spectrometer calibration and measurements of spectral radiance are often required when performing ground, aerial, and space measurements. While calibrating a spectrometer in the field using an integrating sphere is practically unachievable, calibration against a quartz halogen (QH) lamp is a quite easy and feasible option. We describe a calibration protocol whereby a professional QH lamp, opera...
متن کاملVIS-NIR, SWIR and LWIR Imagery for Estimation of Ground Bearing Capacity
Ground bearing capacity has become a relevant concept for site-specific management that aims to protect soil from the compaction and the rutting produced by the indiscriminate use of agricultural and forestry machines. Nevertheless, commonly known techniques for its estimation are cumbersome and time-consuming. In order to alleviate these difficulties, this paper introduces an innovative sensor...
متن کاملestimating soil organic carbon using hyperspectral data in visible, near-infrared and shortwave-infrared (vis-nir-swir) range
background and objectives: soil organic carbon is a main soil property and particularly important for development and sustainable management of agricultural systems. soil organic matter content, which is typically measured in the form of soil organic carbon soc content, is commonly regarded as a key indicator of soil quality and utilization (liu et al., 2015). the presence of som has been prove...
متن کاملAutomatic Shadow Detection in Hyperspectral Vis-nir Images
Depending on the landscape type high amounts of shadow can be present in remote sensing images. These areas are usually masked using shadow detection techniques and excluded from further analysis. Although significant research has been conducted on the detection of shadows there is still room for improvements. In this investigation we focus on the development of a new shadow detection algorithm...
متن کاملEvaluation of Frying Oil Quality Using VIS/NIR Hyperspectral Analysis
Traditional chemical methods of analyzing frying oil quality are time-consuming and not amenable to on-line measurements. The main objective of this study was to evaluate quality changes of heated based on visible/near infrared spectral analysis using a hyperspectroradiometer. The reflectance spectra of the heated oils were analyzed within a range of 400 to 1750 nm. Acid value, total polar comp...
